Installation of ordinary plate rubber bearings

It has the characteristics of simple structure, convenient installation, steel saving, low price, simple maintenance and easy replacement.
By pasting a thick layer of polytetrafluoroethylene on the surface of the plate bearing, a polytetrafluoroethylene sliding rubber bearing can be made. In addition to vertical rigidity and elastic deformation, it can withstand vertical loads and In addition to adapting to the rotation of the beam end, due to the low friction coefficient of the PTFE plate, the beam end can slide freely on the surface of the PTFE plate, and the horizontal displacement is not restricted. It is especially suitable for bridges with medium and small loads and large displacements.
Product division:
1. Rectangular (circular) plate rubber bearing
(1) Performance: This product is made by inlaying, bonding and pressing of multi-layer rubber sheets and thin steel plates. It has sufficient vertical stiffness to bear vertical loads, can reliably transmit the reaction force of the superstructure to the pier, has good elasticity to adapt to the rotation of the beam end, and has large shear deformation to meet the level of the superstructure. Displacement.
(2) Features: This product has been widely used in bridge construction, hydropower projects, and house anti-seismic facilities. Compared with the original steel bearings, it has a simple structure, easy installation, saving steel, low price and easy maintenance. It has the advantages of easy replacement, and the low building height of this product is beneficial to bridge design and cost reduction. It has a good seismic isolation effect and can reduce the impact of live loads and seismic forces on buildings.
2. PTFE skateboard plate rubber bearing
(1) Features: This product is made of a thick layer of PTFE plate bonded to an ordinary plate rubber bearing. In addition to the vertical stiffness and elastic deformation of ordinary plate rubber bearings, which can withstand vertical loads and adapt to beam end rotation, the low friction coefficient (.3) between PTFE and the stainless steel plate at the bottom of the beam can make the upper structure of the bridge Horizontal displacement is unrestricted.
